A telescopic steering apparatus for vehicles includes a locking member movable substantially axially relative to a main shaft, a holder member disposed about the locking member and the main shaft and an operating lever. The main shaft has a tapered end portion engageable with a tapered end portion of the locking member. Both the main shaft and the locking member are provided with projecting portions on their outer peripheries which are engageable with portions of the holder member and the projecting portions of the locking member and the holder member include toothed portions which, when engaged, lock against telescoping of the steering apparatus through displacement of the main shaft.
